TROLLEY-WIRE CROSSING.

San Antonio, in the county of BeXar and State of Texas, have invented acertain new and use-' ful Improvement in Trolley-Wire Crossings, ofwhich the following is a specification.

My invention relates to the improvement of trolley-wire crossings; andthe objects of my invention are to provide a simple and effective deviceof this class by means of which trolley-wires may be made to cross eachother without contact and at the same time admit of the passage oftrolley-wheels over each of the cross-lines, to so construct and arrangemy improved crossing as to admit of its adjustment for the use of linescrossing at different angles, and to produce other improvements thedetails of construction and operation of which will be more fullypointed out hereinafter. These objects I accomplish in the mannerillustrated in the accompanying drawings, in which Figure 1 is anunder-side view of my improved trolley-crossing. Fig. 2 is a sideelevation of the same. Fig. 3 is asectional view on line a: of Fig. 1;and Fig. 4: illustrates in elevation a modified form of crossing-arm thelatter being shown inverted.

Similar numerals refer to similar parts throughout the several views.

In carrying out my invention I employ two metallic crossing-arms, whichare indicated, respectively, at 1 and 2.

The arm 1 consists, as shown, in two triangular end portions 3 and 4,the inner ends of which are connected at the center of their upper sidewith a grooved depression or re-.

cess 8, the latter being adapted to receive and form a seat for adisk-shaped hood 9 of suit- .able insulating'material, said disk or hoodthus being brought flush with the upper side of the arm, to which it issecured.

The remaining arm 2 is, as indicated more clearly in Fig. 3 of thedrawings, of corresponding form with said arm 1, with the exception thatthe bar 10, which connects the triangular portions of said arm 2, isflush With the upper sides of said triangular portions and forms, asshown, a bridge over the space between the inner ends of said portions.

To the under side of this bar or bridge portion 10 is secureddiametrically an insulating-disk 11.

As shown more clearly in Fig. 1 of the drawings, the arms 1 and 2 areadapted to cross each other centrally, the bars and being pivotallyconnected at the centers of their lengths by a bolt 12, which alsopasses loosely through the smaller insulating-disk 11, which bears uponthe ban 5.

As illustrated in Fig.1, the disk 11 is provided adjacent to itsperiphery with an annular row of pin or screw holes 13, through thedesired opposite ones of which pins or screws may be made to pass intothe bar 5, thus admitting of the support of said arm 2 at any desiredangle with the arm 1, as illustrated by the dotted lines in Fig. 1.

14 and 15 represent,respectively,the crossed trolleywires, said wire 14resting in the groove 7 of the upper side of the arm 1 and bearing onthe insulating-hood 9 of said arm, while the wire 15 rests in the grooveof the upper side of the arm 2, thus being made to pass beneath the hood9. These trolley-wires are secured to their respective crossing-arms bymeans of suitable clamps, indicated at 16 and 17.

The manner of utilizing the above-described crossing is substantially asfollows: The two crossing-arms 1 and 2 beingconnected and arranged atproper angles with each other, a trolley-wheel traveling on the wire 1%leaves said wire at the junction of said arm therewith andtraveling'over the lower rounded edge of said arm follows the inclinesthereof until it is again'in contact with said wire 14 at the oppositeendof-said arm, while a trolley-wheel traveling on the wire 15 is in asimilar manner allowed to cross the wire 14 by traveling upon the lowerside of the arm 2. By this operation it will not only be seen that aseparate crossing track or bridge is provided for each trolley-wheel,but that, owing to the employment of the insulating-disk 11, the crossedarms are out of contact with each other, and thus one trolleyline willnot be affected by the current of the other.

Owing to the employment of the hood 9 of insulating material it will beseen that a connection of the two trolley-wires at their crossing-pointsthrough the medium of ice, snow, or water will be obviated.

By the employment of the means which I have described for adjusting thecrossingarms to different angles it will be observed that this crossingmay be employed where two lines cross each other at other angles than aright angle.

I may employ in place of the form of arm shown at 1 and 2 that form ofarm which is shown in an inverted position in Fig. 4, in which thetrolley-wire is bound against the inclined edge of the arm and made tobridge the space between the triangular portions of the latter.

It is obvious that the ti-olley-wire crossing herein shown isexceedingly simple and that the same may be produced at a reasonablecost of manufacture.

Having now fully described my invention, what I claim, and desire tosecure by Letters Patent, is-- 1. In a trolley-wire crossing thecombination with pivotally-connected crossed conducting-arms 1 and 2,each of said arms having triangular end portions and a bar connectingsaid end portions openings in said bar, an insulating-plate between saidbars, and openings in said plate adjacent to its periphery, each of saidbars being adapted to support a trolley-wire longitudinally thereon,substantially as and for the purpose specified.

2. In a trolley-wire crossing the combination with the arms 1 and 2,each of said arms consisting of a central bar portion as described andtriangular end portions, said bar portions being insulated from eachother and pivotally connected, longitudinal grooves in the upper sidesof said arms and an insulating hood or disk flush with and connectingthe upper sides of the triangular portions of the arm 1, substantiallyas and for the purpose specified.
